We describe a case of a 49-year-old diabetic man with a history of myocardial infarction, presenting with deafness for 2 weeks. Initial assessment by otorhinolaryngologists was suggestive of sensorineural hearing loss. Subsequently, the cardiac evaluation showed an apical clot in the left ventricle. Careful neurological reassessment and a cranial MRI yielded a diagnosis of cortical deafness with auditory agnosia secondary to bilateral temporal infarcts. Doppler and MRI ruled out carotid artery thrombosis. The temporal infarcts were therefore considered to be cardioembolic in origin. Cardioembolic stroke is an important differential diagnosis for patients presenting with neurological symptoms on a background of cardiac disease.

A 55-year-old previously healthy Asian Indian man was brought to our hospital with alleged near drowning. He had been found prone in a shallow pool of water in the grounds near his home by his neighbours. The actual circumstances of the event had not been witnessed. At presentation, he was deeply comatose with a Glasgow Coma Scale of 3/15. He was haemodynamically stable, but hypoxic (arterial oxygen saturation: 65% on room air) and gasping. Systemic examination revealed bilateral ocular bobbing (video 1). Oculocephalic reflex was absent. The pupils were bilaterally miotic and responded sluggishly to light. Deep tendon reflexes were normal and symmetrical. Plantar response was bilaterally absent. There were no other focal neurological signs. …

We report the case of a 65-year-old woman presenting with recurrent vomiting for 3 days. She had been previously diagnosed with an atrial septal defect and was on treatment with diuretics and digoxin for paroxysmal supraventricular tachycardia. The clinical examination was consistent with an atrial septal defect with severe pulmonary hypertension. Electrocardiography showed complete heart block with ST-segment changes suggestive of digitalis toxicity. Transthoracic echocardiography confirmed Eisenmengerisation. Serum digoxin levels were elevated. Following hospitalisation, she was diagnosed with photophobia when she persistently asked for ambient lighting to be switched off. Most interestingly, the patient kept reporting seeing little yellow men, which was how she perceived the attending doctors. Cessation of digoxin therapy led to progressive abatement of her symptoms.

We report the case of a 24-year-old man, presenting with fever, headache, vomiting and seizures, subsequently diagnosed with cyanotic congenital heart disease. Evaluation revealed non-obstructive supracardiac total anomalous pulmonary venous connection (TAPVC) as the underlying disorder. Surprisingly, the patient denied any past cardiac symptoms. Presentation in adulthood is infrequent for TAPVC, and primary manifestation with cerebral abscesses is still more unusual.

A 71-year-old Asian-Indian male agriculturist presented with fever since 3 months. Clinical examination revealed hepatosplenomegaly and an early diastolic murmur in the aortic area. Echocardiography confirmed aortic regurgitation with large vegetations on the aortic valve leaflets, and also showed mild left ventricular dilatation with systolic dysfunction. Although blood cultures were persistently sterile, serology for Brucella was strongly positive. On retrospective questioning, the patient confirmed frequent occupational exposure to cattle. Surgical intervention was offered, but refused by the patient on financial grounds. Medical therapy for brucellosis with rifampicin, doxycycline and streptomycin resulted in complete and durable recovery.

We describe a 34-year-old man with an ostium secundum atrial septal defect, Ebstein's anomaly of the tricuspid valve with severe tricuspid regurgitation, congenital valvular pulmonary stenosis, rheumatic mitral stenosis and regurgitation with aortic regurgitation, who presented with decompensated heart failure after developing atrial fibrillation. The complex haemodynamic interplay of these lesions is also discussed.

We report the case of a 40-year-old housewife, who presented with vomiting since past 5 days and weakness of all four limbs since 1 day. Clinical examination confirmed the presence of flaccid quadriparesis with preserved tendon reflexes. Routine laboratory parameters showed severe hypokalaemia. On further evaluation she was diagnosed to have type 1 renal tubular acidosis secondary to Sjogren's syndrome. Sicca symptoms were conspicuous by their absence.

Absent pulmonary valve syndrome (APVS) is a rare congenital cardiac anomaly. This syndrome is comprised of subtotal or total absence of pulmonary valve leaflets, stenosis of the pulmonary artery orifice, aneurysmal dilation of the main pulmonary artery and ventricular septal defect. We report a case of APVS with neural tube defect detected prenatally at 22 weeks of gestation by echocardiography, and subsequently confirmed by autopsy of the still born fetus. The common presentations, means of diagnosis and variants of APVS are discussed in brief.

We report the case of a 70-year-old man with pancytopaenia and new-onset recurrent generalised seizures. Detailed evaluation yielded a diagnosis of vitamin B(12) deficiency. He was treated with parenteral vitamin B(12) supplementation and antiepileptic drugs. Seizures are an unusual manifestation of vitamin B(12) deficiency and possible mechanisms of epileptogenesis are discussed.

A 22-year-old man, diagnosed 7 weeks before with pulmonary tuberculosis and started on antitubercular therapy, presented with non-exertional retrosternal chest pain since the past week. He was diagnosed on the strength of thoracic radiograms and CT imaging to have a mediastinal abscess, which was percutaneously drained. He was continued on the same regimen of drugs. Analysis of the fluid obtained was suggestive of tuberculous aetiology. Steroids were not required.

A 50-year-old Asian Indian female with known hypertension presented with persistent vomiting but no other symptoms of meningism. Clinical examination and basic laboratory parameters were entirely normal except for significant hyponatremia. Further investigation was suggestive of the syndrome of inappropriate antidiuretic hormone (SIADH) secretion. Subsequently, despite steady correction of hyponatremia, the patient developed generalised seizures. Cerebrospinal fluid (CSF) analysis performed was inconclusive. Screening for a chronic meningitis underlying SIADH, yielded positive blood and CSF titres for venereal disease research laboratory (VDRL), which were confirmed by Treponema pallidum haemagglutination (TPHA). The patient was treated for neurosyphilis and made a complete recovery. Hyponatremia resolved and she had no further episodes of seizures. She was tested for HIV infection which was negative. On follow-up, she remained TPHA positive but VDRL titres became negative.

Although well-known as a complication of other hypoxic conditions such as near drowning, status asthmaticus and carbon monoxide poisoning, rhabdomyolysis has not been reported in patients with hanging. The authors report a case of partial hanging complicated by rhabdomyolysis and acute kidney injury.

Objective To identify characteristic features of tuberculosis in patients with culture proven brucellosis. Methods A retrospective analysis was performed on patients diagnosed with culture proven brucellosis between January and December 2011, based on review of their medical records. Patients with demonstrable co-infection with tuberculosis were excluded. Clinical features, laboratory parameters and tissue histopathology reports where available were noted. Results Thirty-two patients with brucellosis were included in the study. Twenty-one (65.63%) patients had chronic fever, thirteen (40.63%) had a productive cough, while significant weight loss, evening rise of temperature and night sweats were reported by eight (25.00%), eleven (34.38%) and five (15.63%) patients respectively. Nine (28.13%) patients had at least three of these symptoms. Lymphadenopathy, hepatomegaly and splenomegaly were noted on examination in seven (21.88%), fifteen (46.88%) and twelve (37.50%) patients respectively. Eight (25.00%) patients had hepato-splenomegaly, of these only two had associated significant lymphadenopathy. Respiratory examination was normal in all patients. Elevated ESR greater than 50 mm/hr was seen in eight (25.00%), it was greater than 100 mm/hr in five (15.63%) patients. Hypergammaglobulinemia was seen in eight (25.00%) cases. Bone marrow biopsy showed non-caseating granulomas in three (9.38%) cases, lymph node biopsy showed granulomas in one case. Overall, three (9.38%) patients had known risk factors for tuberculosis, while six (18.75%) had risk factors for brucellosis. Conclusions There is a clear overlap between brucellosis and tuberculosis both in terms of clinical presentation and laboratory parameters. It is essential to carefully rule out tuberculosis in all cases of suspected or proven brucellosis before initiating antimicrobial therapy, in order to forestall development of drug-resistant tuberculosis.

A 38-year-old housewife presented with a 3-month history of gradually progressive fatigue and deepening jaundice as well as a history of mild fluctuating jaundice since childhood. General examination revealed an obvious icterus. Systemic examination was normal. Laboratory tests confirmed unconjugated hyperbilirubinaemia. Further evaluation yielded a diagnosis of vitamin B12 deficiency on a background of Gilbert's syndrome.

A 40-year-old previously healthy male presented with acute onset painless dimness of vision in both eyes since the past week and low-grade fever, anorexia and weight loss for the past 1 month. He had been evaluated at a local hospital and diagnosed to have a posterior cerebral artery territory infarct on the left side on the strength of cranial CT. Shortly after receiving antiplatelets and warfarin he had developed severe coagulopathy as evidenced by haematemesis, epistaxis and haematuria. Preliminary investigation revealed prolonged clotting parameters, renal failure and anaemia. Cerebral MRI showed multiple areas of cortical haemorrhage. In the course of his hospital stay, he developed further stigmata of auto-immunity including Coomb’s positive haemolytic anaemia, recurrent venous thromboses and a palpable purpuric truncal rash. He was eventually diagnosed to have an adenocarcinoma of the lung, and was subsequently referred to an oncologist for further therapy.

We report a 27-year-old previously healthy man, who presented with fever and painful swelling of both ankles for 6 months, and who had been jaundiced for 1 week. Clinical examination revealed diffuse macular rash, severe pallor, deep icterus, generalised lymphadenopathy and hepatosplenomegaly. Detailed evaluation revealed granulomata in bone marrow aspirate, and numerous acid fast bacilli in lymph node biopsy. Bone marrow PCR was also positive for Mycobacterium tuberculosis. A diagnosis of disseminated tuberculosis was made and antitubercular therapy was initiated. Investigation also showed features of haemophagocytosis within the bone marrow. Results of further tests satisfied the criteria for haemophagocytic lymphohistiocytosis, probably secondary to tuberculosis. However, rapid deterioration in his clinical condition led to his death within 5 days of diagnosis, before appropriate therapy for haemophagocytic lymphohistiocytosis could be instituted. This case report highlights an unusual and deadly presentation of tuberculosis in an immunocompetent individual.

We report the case of a 30-year-old housewife who presented with fever and lower abdominal pain, and was diagnosed with an adnexal collection. Initial evaluation was suggestive of tubercular pelvic inflammatory disease (PID). Subsequently, from a culture of pus aspirated from the collection grew out Nocardia species. She was treated with amikacin and cotrimoxazole and made a complete recovery. Clinical and laboratory evaluation for immunosuppression was negative. Primary abdominal nocardiosis is an unusual cause for PID and an important differential diagnosis for tuberculosis.

We report the case of a young male who presented with features of aseptic meningitis and elevated serum liver enzymes, but no symptoms or signs suggestive of an acute hepatitis. Subsequently, he was diagnosed with dual infection with hepatitis A and E viruses, and recovered completely with symptomatic therapy. Isolated aseptic meningitis, unaccompanied by hepatitic features is an unusual presentation of a hepatotrophic viral infection, and is yet to be reported with hepatitis A and E virus co-infection.

Diffuse myositis with progression to rhabdomyolysis has been reported in association with wide range of viral infections. We report a case of polymyositis-like syndrome complicated by rhabdomyolysis secondary to brucellosis. This case report thus contributes yet another atypical presentation to a disease already infamous for its protean manifestations.

Many chest pain patients are admitted to the hospital annually without coronary artery disease. In 1992, we randomized patients to direct admission versus a 4-hour serial cardiac marker protocol that led to the development of the 4-hour rule-out protocol. Our study demonstrated that patients could
